Seals that have been damaged
Window seals hold the gas argon or krypton between glass panes in triple or double-pane windows, and they can wear out over time. A damaged seal allows air from outside to pass through and the argon gas used to insulate your home to escape. Both of these are harmful to energy efficiency.
The reason window seals fail is because they are exposed to extreme temperatures and humidity, as well as pressure. These changes cause your window glass to expand and shrink, which puts a lot of pressure on the seals over time. This can also happen if you have pets or children who accidentally hit your windows.
